Title: Surgical apparatus and anvil delivery system therefor
Inventor: GREEN DAVID T
IPC: A61B17/00
Filed: 1993-05-10
Abstract: An apparatus for delivering a surgical device to a predetermined location within a tubular organ includes an elongated delivery member having a proximal and a distal end, a mounting mechanism for detachably mounting the surgical device at the distal end of the elongated delivery member and a releasing mechanism for releasing the surgical device from the mounting mechanism.     A detachable anvil assembly for use with an apparatus for performing circular anastomosis of tubular organs includes an elongated anvil rod having proximal and distal end portions and an anvil head mounted to the distal end portion of the anvil rod.  The distal end portion is pivotally mounted and is adapted to pivot approximately plus or minus ninety degrees relative to a longitudinal axis defined by the rod.  An elongated delivery member detachably receives the anvil assembly and facilitates delivery of the anvil assembly to the operative site.  The pivoting feature of the distal end reduces the transverse profile of the assembly which consequently facilitates introduction and advancement of the anvil assembly within the tubular organ.

Title: Weld seam covering on metal tubes
Inventor: BALTENSPERGER WALTER
IPC: B29C63/26
Filed: 1993-09-27
Abstract: ABSTRACT       In the process for the continuous application of protective layers to cover a longitudinal weld seam of metal tubes, a hot-melt mass is passed continuously as a flexible hot-melt thread  (28,58)  through the welding arm  (18)  of a welding machine,  deflected to the inside of the longitudinal weld seam of the metal tubes,  pressed by an application device (40,54), melted and spread homogenously over the width of the longitudinal weld seam (12).  Preferably at the same time as the inner coating, an outer protective layer is applied which allows the elimination of the baking or drying ovens  for lacquer with their high requirements for space and energy.     One particularly advantageous application of the process lies in  the  application  of  a  sterilisation-resistant  hot-melt strip to the inside or inside and outside of the longitudinal weld seam of a tin casing.              (Fig. 3)

Abstract: A pair of main beams, a plurality of diagonal cross braces and transverse beams having a beam height of about 75% of prior art main beam heights provide a relatively flexible chassis.  A clamp assembly central of the chassis clamps a cubicle cargo container central region to the chassis to rigidify the chassis.  The cargo container is connected to the chassis front and rear by conventional bolster pin and twist lock assemblies.  An upper container casting has an opening for receiving an interbox twist lock connector aligned on an axis closely spaced to the side panels of upper and lower containers on a rail car to minimize bending loads on lower container intermediate support posts.  Lower castings at the base of each of the intermediate posts mate with a lower container upper castings in a stacked arrangement on a rail car.  The chassis has a bogie assembly receiving channel for slidably receiving a bogio locked to the chassis by a conventional retractable pin mechanism.  The container tunnel has a trapezoidal transverse section which mates with a chassis goose neck which is 10% narrower than and about 50% the vertical height of prior goose necks.

Abstract: The initial stages in the manufacture of a glass-like mineral fiber suitable for a multiplicity of industrial uses are essentially conventional; a charge of raw minerals (igneous rock, basalt, slag from a blast furnace or other metal working furnace, phosphate slag, etc.) is melted, then spun and collected to produce a fibrous mineral "blanket".          The "blanket" is chopped up, separated, and screened, producing a prilled material constituting a multiplicity of mineral fiber pellets of given average size.  These pellets are subjected to brief, rapid acceleration, as by contact with a high-speed toothed rotary wheel, to accelerate and stress the pellets into an industrially usable material constituting a multiplicity of shredded, flake-like mineral fiber elements, at least one such element for each pellet.

Title: Ring cutting and removing device
Inventor: HAN SANG I
IPC: A61B19/00
Filed: 1994-03-15
Abstract: ABSTRACT    A combination ring cutting and removing device is provided for use by medical personnel for cutting and removing rings from injured or swollen fingers.  If the finger that carries a ring is badly injured, the swelling of the injured finger often precludes the removal of the ring.  The ring must be cut in order to restore circulation to the swollen finger.  The combined ring cutting and ring removing device is provided in the form of a plier-type cutting device with a built in means for prying the cut ring apart so the ring can be removed from a swollen finger.          The device may also be used for non-medical applications that require a cutting action followed by a prying or separating action.

Title: Apoptosis specific tp30 protein
Inventor: WANG EUGENIA
IPC: C07K14/47
Filed: 1994-12-23
Abstract: Apoptosis or programmed cell death is a tightly regulated mechanism used by the body to eliminate excess cells in a given tissue.  If this mechanism fails, resulting in too may cells, cancer may develop in certain tissues.  If the mechanism is overactive, resulting in the destruction of too many cells, tissue degeneration can occur.  Therefore being able to identify which cells are destined to undergo apoptosis is critical in allowing clinicians, pathologists and researchers to develop means to detect, diagnose or treat disorders wherein the natural regulation of cell death events is interrupted.  The present inventor has identified a 30 kDa protein, designated Tp30, that is specific for cells that are programmed to die.  A monoclonal antibody specific for Tp30 has also been identified.  The Tp30 protein and monoclonal antibodies thereto are useful in the detection and therapy of disorders wherein the natural regulation of cell death events is interrupted.  Such disorders include cancer, bone degeneration, autoimmune diseases, neurodegenerative diseases, cardiovascular disorder, ischemia, HIV-associated illness and kidney malfunction.
